Abstract
The object of the invention is a device for measuring the surface pressure of a film formed at the interface of a liquid and gaseous phase, the device comprising a detector means and a sensor means. The detector means comprises a light source and a position-sensitive detector, the active surface of which is situated in the light beam of the light source, and the sensor means comprises a sensor which can be brought into contact with the film to be measured, and a shading means which, in correspondence with the force applied to the sensor by the film, moves in the light beam between the active surface of the detector and the light source.
